"VRTs are useful for visualizing spatial relationships, such as defining the course of coronary anomalies and the presende and course of coronary artery bypass grafts. This technique finds much more use in the analysis of thoracic cardiovascular anatomy, in congenital heart disease, and for teaching purposes and illustrations for patients."
SCCT guidelines for the interpretation and reporting of coronary computed tomographic angiography
Raff GL et al.
J Cardiovasc Comput Tomogr 2009 March-April; 3(2):122-136- MIP is CCTA Interpretation
- Allows visualization of long vessel segments
- Tends to reduce percieved noise
- Loss of lesion information within slab volume especially for low density structures
- Attenuation values not accurately defined (high values are all that is displayed) - ACC/AHA/SCCT Standards
- Level 1 50 coronary CTA over 4 weeks
- Level 2 150 coronary CTA over 8 weeks
- Level 3 300 coronary CTA over 6 months " Levels of training, as currently suggested by the American College of Cardiology Foundation and the American heart Association, may be insufficient to become an independent practitioner of coronary CT angiography."
Learning Curve for Coronary CT Angiography: What Constitutes Sufficient Training?
Pugliese F et al.
Radiology 2009; 251:359-368"In conclusion, although inexperienced physicians improved their diagnostic performances by increasing their experience with coronary CT angiography, it may take a prolonged time to gain the expertise to read coronary CT angiograms as an independent practitioner, which should have implications for training under existing guidelines."

Radiology 2009; 251:359-368"Increasing experience with coronary CT Angiography improved the diagnostic performance of inexperienced physicians. However, acquiring expertise in coronary CT angiography was slow and may take more than 1 year."
